Phantoms and home cinema

[fgueho]

As another post put it, you need the DIALOG box to control and delay the video image as processing the audio takes time (As Sonos demonstrates).
I think it will all be sorted when we see a DIALOG box with an HDMI input.

I don't think an HDMI input will be the solution.
Because :
1 - It would also need an HDMI output to send the video feed in sync.
2 - It would need multiple HDMI inputs, because people have multiple sources (bluray, tv, playstation, etc.)
3 - It would (sort of) replace an AV Reciver but with far less options, and far less power

What I don't understand is that my AV Receiver use an optical input for the sound. And there is no delay with the video feed (which doesn't go through my AV Receiver but directly link to my TV).

I have multiple sources :
Playstation (video) => HDMI link to my TV
Playstation (audio) => optical link to my AV receiver
TV (video) => HDMI link to my TV
TV (audio) => optical link to my AV receiver
PCHC (video) => HDMI link to my TV
PCHC (audio) => optical link to my AV receiver

So in all cases, the audio and video go separate ways. The video always goes directly to the TV, the audio always goes directly to my AV Receiver.
And I don't have any delay.

So how come my AV Receiver is capable of processing the optical audio source without delay, and not the phantoms?
